Description

Technical Field

[0001] This invention relates to the field of fire protection equipment technology, specifically to an intelligent detection and coordinated response device for fire hazards in charging stations based on the Internet of Things. Background Technology

[0002] With the widespread adoption of electric vehicles, the number of charging stations has surged, but the fire hazards have also become increasingly prominent. During operation, charging stations may catch fire due to battery overheating, short circuits, or external factors. Traditional firefighting methods often rely on basic smoke sensors or manual inspections, lacking intelligent, comprehensive monitoring and rapid response capabilities. The complex environment of charging stations, including high temperatures, high humidity, and electromagnetic interference, places higher demands on the reliability of firefighting equipment.

[0003] Currently, the development of IoT technology has made it possible to integrate remote monitoring and data transmission in fire protection systems. However, existing technologies still have many shortcomings in practical applications, specifically as follows:

[0004] First, existing technologies mostly rely on a single smoke sensor for fire early warning. Traditional charging piles are only equipped with fixed smoke sensors, which cannot fully detect abnormal temperatures or local overheating. This single sensor mode is prone to false alarms or missed alarms, especially in environments where there are many vehicles and devices intertwined at charging stations, and cannot cover blind spots.

[0005] Second, most infrared temperature measurement cameras in the existing technology are statically deployed, which leads to a delay in the identification of local overheating or early fire sources, increasing the risk of fire spreading.

[0006] Third, existing fire extinguishing systems often use fixed nozzles or simple spraying devices, which have limited coverage of the extinguishing agent. Existing methods may not be able to achieve the reciprocating motion of the atomizing nozzles, resulting in uneven aerosol spraying.

[0007] In view of this, the present invention proposes an intelligent detection and coordinated response device for fire hazards in charging stations based on the Internet of Things. Summary of the Invention

[0008] This invention proposes an intelligent detection and coordinated response device for fire hazards in charging stations based on the Internet of Things, which solves the problem of inaccurate early warning by a single smoke sensor in the prior art.

[0009] The technical solution of the present invention is as follows: A smart detection and linkage response device for fire hazards in charging stations based on the Internet of Things (IoT) includes a charging pile. Smoke sensors are fixedly connected to both sides of the charging pile. A temperature measuring mechanism is installed on the charging pile.

A hollow shaft penetrating the side wall of the protective box is rotatably connected to one side of the protective box. A turntable is fixedly connected to one end of the hollow shaft. A rotating seat is rotatably connected to the outer side of the turntable. An infrared temperature measuring camera is fixedly connected to the outer side of the rotating seat. A first bevel gear is coaxially fixedly connected to the rotating seat. A rotating shaft penetrating the hollow shaft is rotatably connected to the inner side of the hollow shaft. A second bevel gear meshing with the first bevel gear is fixedly connected to one end of the rotating shaft. A driving component for driving the turntable to rotate is installed inside the protective box. An IoT module connected to a remote control monitoring center is fixedly connected to the charging pile. The smoke sensors and the infrared temperature measuring camera are electrically connected to the IoT module. A fire extinguishing mechanism for extinguishing fires is installed inside the charging pile.

[0010] Preferably, the driving component includes a first motor fixedly installed inside the protective box, the output shaft of the first motor is fixedly connected to a first gear, and the other end of the hollow shaft is fixedly connected to a second gear, the second gear meshing with the first gear.

[0011] Preferably, the driving component further includes a third gear fixedly connected to the output shaft of the first motor, a fourth gear rotatably connected to the inner side of the protective box, the fourth gear meshing with the third gear, an incomplete gear fixedly connected to the fourth gear on the same axis, a fifth gear fixedly connected to the other end of the rotating shaft, the incomplete gear intermittently meshing with the fifth gear through rotation, a torsion spring sleeved on one end of the rotating shaft, and the two ends of the torsion spring being welded to the fifth gear and the inner wall of the protective box, respectively.

[0012] Preferably, the fire extinguishing mechanism includes a mounting box fixedly connected to the inside of the charging pile. A second motor is fixedly installed inside the mounting box. A reciprocating screw is fixedly connected to the output shaft of the second motor. A slider is threaded onto the reciprocating screw. The slider is slidably connected to the inner wall of the charging pile. An atomizing nozzle is fixedly connected to the bottom of the slider. A liquid guiding hose is fixedly connected to the inlet end of the atomizing nozzle. An aerosol supply component is provided at the inlet end of the liquid guiding hose, which, driven by the second motor, guides aerosol into the liquid guiding hose. A winding component is provided inside the charging pile, which, through the translation of the slider, retracts and extends the liquid guiding hose.

[0013] Preferably, the aerosol supply component includes a liquid pump fixedly installed inside the charging pile, an aerosol extraction tube fixedly connected to the inlet end of the liquid pump, an aerosol storage tank fixedly connected to the inlet end of the aerosol extraction tube, the aerosol storage tank fixedly connected to the inside of the charging pile, and the outlet end of the liquid pump connected to the inlet end of the liquid guiding hose.

[0014] Preferably, the aerosol supply component further includes a first bevel gear fixedly connected to the impeller of the liquid pump on the same axis, and a second bevel gear fixedly connected to the output shaft of the second motor, wherein the second bevel gear meshes with the first bevel gear.

[0015] Preferably, the ratio of the number of teeth of the first bevel gear to the number of teeth of the second bevel gear is 1:6.

[0016] Preferably, the winding component includes a mounting bracket fixedly connected to one end of the slider, and a drum is rotatably connected to the inner side of the mounting bracket, and the liquid guiding hose is wound onto the drum.

[0017] Preferably, a sixth gear is coaxially fixedly connected to one end of the drum, and a toothed plate is fixedly connected to the inner side of the charging pile, which is parallel to the reciprocating lead screw. The sixth gear meshes with the toothed plate.

[0018] Preferably, the charging pile has a control panel on its inner side. The control panel includes a processor, a communication module electrically connected to the processor, and the communication module is signal-connected to an Internet of Things (IoT) module. The smoke sensor and the infrared temperature measurement camera are both signal-connected to the processor, and the second motor is electrically connected to the processor.

[0019] The working principle and beneficial effects of this invention are as follows:

[0020] 1. By installing smoke sensors on both sides of the charging pile and combining them with infrared temperature cameras, dual-parameter monitoring of smoke and temperature is achieved. This multi-sensor data fusion method effectively reduces the risk of false alarms and missed alarms, and improves the accuracy of fire early warning. For example, the smoke sensor can detect the concentration of ambient smoke, while the infrared temperature camera can identify local overheating or early fire sources, complementing each other to cover the complex environment of the charging station.

[0021] 2. The infrared temperature measuring camera in the temperature measuring mechanism achieves spherical scanning through multi-degree-of-freedom motion (such as rotation and oscillation), avoiding the monitoring blind spots of traditional static arrangements. The drive component controls the camera's intermittent oscillation and continuous rotation, enhancing scanning coverage and ensuring monitoring without blind spots.

[0022] 3. The fire extinguishing mechanism uses a second motor to drive a reciprocating screw, which in turn causes the slider to move the atomizing nozzle in a reciprocating translational motion. This dynamic spraying method significantly increases the aerosol coverage area, and compared to fixed nozzles, the extinguishing agent is distributed more evenly, thus improving the fire extinguishing effect.

[0023] 4. The aerosol supply unit uses gear transmission to ensure synchronous operation of the liquid pump and the second motor, achieving a continuous supply of extinguishing agent. The liquid pump draws extinguishing agent from the aerosol storage tank and delivers it to the atomizing nozzle through the liquid delivery hose. The flow rate is matched with the nozzle movement to avoid interruption. The winding unit uses a slider to drive the drum to rotate (through the engagement of the sixth gear and the gear plate), automatically winding and unwinding the liquid delivery hose to prevent hose tangling or wear, ensuring unobstructed pipeline flow during fire extinguishing. No additional power is required, making it energy-efficient and highly effective.

[0024] 5. The sensor data and alarm information are transmitted to the remote monitoring center through the Internet of Things module, supporting real-time monitoring and historical data analysis, which facilitates timely intervention and early warning by maintenance personnel and improves the intelligence level of charging station management; the processor integrates control of smoke sensors, infrared temperature measurement cameras and fire extinguishing mechanisms to realize a closed loop of "monitoring-analysis-disposal", reduce manual intervention and improve emergency response efficiency.

[0036] The technical solutions of the present invention will be clearly and completely described below with reference to the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0037] like Figures 1 to 9 As shown, this embodiment proposes an intelligent fire hazard investigation and linkage response device for charging stations based on the Internet of Things, including a charging pile 1. Smoke sensors 2 are fixedly connected to both sides of the charging pile 1. A temperature measuring mechanism 3 is installed on the charging pile 1. The temperature measuring mechanism 3 includes a protective box 31 fixedly connected to the outer wall of the charging pile 1. A hollow shaft 32 penetrating the side wall of the protective box 31 is rotatably connected to one side of the protective box 31. A turntable 33 is fixedly connected to one end of the hollow shaft 32. A rotating seat 34 is rotatably connected to the outer side of the turntable 33. An infrared temperature measuring camera 3 is fixedly connected to the outer side of the rotating seat 34. 5. A first bevel gear 36 is coaxially fixedly connected to the rotating seat 34. A rotating shaft 37 that passes through the hollow shaft 32 is rotatably connected to the inner side of the hollow shaft 32. A second bevel gear 38 that meshes with the first bevel gear 36 is fixedly connected to one end of the rotating shaft 37. A driving component 39 for driving the turntable 33 to rotate is provided inside the protective box 31. An Internet of Things (IoT) module that is connected to the remote control monitoring center is fixedly connected to the charging pile 1. The smoke sensor 2 and the infrared temperature measuring camera 35 are both electrically connected to the IoT module. A fire extinguishing mechanism 4 for extinguishing fires is provided inside the charging pile 1.

[0038] In this embodiment, a smoke sensor 2 is fixedly installed on both sides of the charging pile 1 as the main body to monitor the ambient smoke concentration in real time. A temperature measuring mechanism 3 is installed on the outer wall of the charging pile 1 and scans for abnormal ambient temperatures using an infrared temperature measuring camera 35. When either the smoke sensor 2 or the infrared temperature measuring camera 35 detects a potential hazard, the signal is transmitted to the processor on the control panel, triggering the automatic activation of the fire extinguishing mechanism 4 for coordinated response. The integration of IoT technology allows for remote monitoring and data transmission; the combination of smoke and temperature sensors covers multiple potential hazards within the charging station, improving detection accuracy.

[0039] The hollow shaft 32 is driven to rotate by the drive component 39, causing the turntable 33 fixed at its end to rotate. The rotating seat 34 on the turntable 33 meshes with the second bevel gear 38 through the first bevel gear 36. When the rotating shaft 37 is driven, the infrared temperature measuring camera 35 can simultaneously revolve (around the charging pile) and rotate (tilt at multiple angles) to achieve spherical scanning. The drive component 39 controls the rotation rhythm to ensure that the camera periodically covers the entire area. The camera's multi-degree-of-freedom movement eliminates monitoring blind spots and accurately identifies local overheating or fire sources.

[0040] In a further preferred embodiment of the present invention, the driving component 39 includes a first motor 391 fixedly installed inside the protective box 31. The output shaft of the first motor 391 is fixedly connected to a first gear 392. The other end of the hollow shaft 32 is fixedly connected to a second gear 393, which meshes with the first gear 392. A third gear 394 is fixedly connected to the output shaft of the first motor 391. A fourth gear 395 is rotatably connected to the inside of the protective box 31, which meshes with the third gear 394. An incomplete gear 396 is coaxially fixedly connected to the fourth gear 395. A fifth gear 397 is fixedly connected to the other end of the rotating shaft 37. The incomplete gear 396 intermittently meshes with the fifth gear 397 through rotation. A torsion spring 398 is sleeved on one end of the rotating shaft 37. The two ends of the torsion spring 398 are welded to the fifth gear 397 and the inner wall of the protective box 31, respectively.

[0041] In this embodiment, the first motor 391 drives the second gear 393 through the first gear 392, causing the hollow shaft 32 and the turntable 33 to rotate at a constant speed. Simultaneously, the third gear 394 meshes with the fourth gear 395, causing the incomplete gear 396 to rotate intermittently. When the incomplete gear 396 meshes with the fifth gear 397, the rotating shaft 37 rotates, and the infrared temperature measuring camera 35 swings through bevel gear transmission. When the meshing disengages, the torsion spring 398 resets the rotating shaft 37, achieving periodic swinging of the camera. The intermittent swinging of the infrared temperature measuring camera 35, combined with continuous rotation, enhances scanning coverage and avoids data omissions. The torsion spring 398's buffering mechanism reduces gear impact and improves durability.

[0042] In a further preferred embodiment of the present invention, the fire extinguishing mechanism 4 includes a mounting box 41 fixedly connected to the inner side of the charging pile 1. A second motor 42 is fixedly installed on the inner side of the mounting box 41. A reciprocating screw 43 is fixedly connected to the output shaft of the second motor 42. A slider 44 is threaded onto the reciprocating screw 43. The slider 44 is slidably connected to the inner wall of the charging pile 1. An atomizing nozzle 45 is fixedly connected to the bottom of the slider 44. A liquid guiding hose 46 is fixedly connected to the inlet end of the atomizing nozzle 45. An aerosol supply component 47 is provided at the inlet end of the liquid guiding hose 46, which, driven by the second motor 42, guides aerosol into the liquid guiding hose 46. A winding component 48 is provided on the inner side of the charging pile 1, which, through the translation of the slider 44, winds up and unwinds the liquid guiding hose 46.

[0043] In this embodiment, when a fire occurs, the second motor 42 starts and drives the reciprocating screw 43, causing the slider 44 to slide back and forth along the inner wall of the charging pile 1. The aerosol supply component 47 dynamically sprays aerosol to the atomizing nozzle 45 through the liquid guiding hose 46 to extinguish the fire, which greatly increases the coverage area of ​​the aerosol sprayed from the atomizing nozzle 45, thereby improving the fire extinguishing effect. The winding component 48 moves synchronously to ensure that the liquid guiding hose 46 is wound and unwound in an orderly manner, avoiding the problem of the liquid guiding hose 46 getting tangled and affecting the flow of aerosol.

[0044] In a further preferred embodiment of the present invention, the aerosol supply component 47 includes a liquid pump 471 fixedly installed inside the charging pile 1. The inlet end of the liquid pump 471 is fixedly connected to a suction tube 472, and the inlet end of the suction tube 472 is fixedly connected to an aerosol storage tank 473. The aerosol storage tank 473 is fixedly connected inside the charging pile 1. The outlet end of the liquid pump 471 is connected to the inlet end of the liquid guiding hose 46. The impeller of the liquid pump 471 is coaxially fixedly connected to a first bevel gear 474. The output shaft of the second motor 42 is fixedly connected to a second bevel gear 475. The second bevel gear 475 meshes with the first bevel gear 474, and the gear ratio of the first bevel gear 474 to the second bevel gear 475 is 1:6.

[0045] In this embodiment, the output shaft of the second motor 42 drives the first bevel gear 474 (gear ratio 1:6) via the second bevel gear 475, which in turn rotates the impeller of the liquid pump 471. The liquid pump 471 draws aerosol from the storage tank 473 through the suction pipe 472 and pumps it into the liquid guiding hose 46, which is then atomized and sprayed out by the atomizing nozzle 45. The gear transmission ensures that the liquid pump and the second motor 42 work synchronously; the gear transmission ratio is optimized, and the flow rate of the liquid pump 471 is matched with the movement of the atomizing nozzle 45, ensuring a continuous supply of extinguishing agent.

[0046] In a further preferred embodiment of the present invention, the winding component 48 includes a mounting bracket 481 fixedly connected to one end of the slider 44, a drum 482 rotatably connected to the inner side of the mounting bracket 481, a liquid guiding hose 46 being wound onto the drum 482, a sixth gear 483 being coaxially fixedly connected to one end of the drum 482, and a toothed plate 484 arranged parallel to the reciprocating lead screw 43 being fixedly connected to the inner side of the charging pile 1, with the sixth gear 483 meshing with the toothed plate 484.

[0047] In this embodiment, when the slider 44 moves, the mounting bracket 481 fixed on it drives the drum 482 to move horizontally; the sixth gear 483 at one end of the drum 482 meshes with the fixed tooth plate 484, forcing the drum to rotate and automatically retracting the liquid guiding hose 46, which prevents the hose from getting tangled or worn during movement; the orderly retraction and retraction of the liquid guiding hose 46 ensures unobstructed pipeline during fire extinguishing; no additional power is required, and the movement of the slider drives the process, making it energy-efficient and effective.

[0048] In a further preferred embodiment of the present invention, a control panel is provided on the inner side of the charging pile 1. The control panel includes a processor and a communication module electrically connected to the processor. The communication module is signal-connected to the Internet of Things module. The smoke sensor 2 and the infrared temperature measuring camera 35 are both signal-connected to the processor. The second motor 42 is electrically connected to the processor.

[0049] In this embodiment, when sensor data is abnormal (such as excessive smoke or a sudden temperature rise), the processor analyzes the signal, triggers the fire extinguishing mechanism 4 to start, and sends an alarm to the remote monitoring center through the Internet of Things module. The second motor 42 starts and drives the reciprocating screw 43, causing the slider 44 to slide back and forth along the inner wall of the charging pile 1. The aerosol supply component 47 dynamically sprays aerosol fire extinguishing onto the atomizing nozzle 45 through the liquid guiding hose 46, which greatly increases the coverage area of ​​the aerosol sprayed from the atomizing nozzle 45, thereby improving the fire extinguishing effect. Multi-sensor data fusion reduces the false alarm rate and improves response accuracy. The Internet of Things supports real-time monitoring and data analysis, which is convenient for maintenance and early warning.

[0050] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
